A mutation in a plant prevents the proper synthesis of pectin. Which tissue would be MOST directly affected by this mutation and what would be the primary consequence?
Sclerenchyma; decreased rigidity in mature tissues
Parenchyma; reduced storage capacity
Collenchyma; reduced flexible support in growing regions
Xylem; impaired water transport
